5. The "Facebook killer" is dead. Steve Stephens posted a video of himself shooting and killing a man on Facebook on Sunday. Since then there had been a nationwide manhunt for him in the US. On Tuesday afternoon police said he died of an apparent self-inflicted gunshot wound to the head after a brief pursuit by Pennsylvania state police. Before the car chase, however, Stephens stopped at a McDonald's drive-thru where employees held up his french fry order and tipped off the police.
